MEASURING DEVICE.

Application filed Hatch 27, 1922. Serial No. 547,382.

To all whom-it may concern:

Be it known that I, REID W. THOMPSON, a

. citizen of the United States of America, and

resident of Turner, Jasper County, Iowa, have invented a new and useful Measuring Device, of which the following is a specification.

An object of this invention is to provide improved means for receiving and containing predetermined. quantities of substance, such as beans, coffee and the like, and delivering them to a bag, carton or package.

A further object of this invention is to provide improved means for controllingthe flow of substance from a store thereof by connections with a receiving container.

A further object of this invention is to provide improved means for counter-balancing a receiving container and the contents thereof.

A further object of this invention is to provide improved means for retaining and discharging the contents of a receiving container.

My invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in the claims and illustrated by the accompanying drawing, in which- Figure 1 is an elevation of my improved device, parts being broken away to reveal. interior construction. Figure 2 is a plan of the device. Figure 3 is a bottom plan of parts of the device.

In the construction of the device as shown the numeral 10 designates a down-spout or chute leading from a hopper 11 adapted to contain a store of substance to be removed and measured. The hopper and chute may be supported in any suitable manner such as by legs 12 secured thereto. Brackets 13, 14 are mounted transversely on and project at each end from the chute 10 and wheels 15, 16 are pivoted between end portions of said brackets. A lever 17 is fulcrumed on one side of the chute below the bracket 13 and projects equally from its fulcrum. Connecting rods 18, 19 are pivoted at their inner ends to end portions of the lever 17 and extend oppositely therefrom substantially in parallel planes. The outer ends of the rods 18, 19 are turned inwardly and pivoted to lower portions of the wheels 15, 16, thus connecting said wheels for simultaneous oscillation. Hanger bars 20, 21 are points on the wheel 15, 16 and depend therefrom in converging planes. The lower end portions of the hanger bars 20, 21 are pivoted to and support a container 22 located beneath and spaced from the .lower end of the chute 10. Valves 23, 2 1 are slidingly mounted in registering slots in opposite side walls of the chute 10 and rods 25, 26 pivot: ally connect the outer ends of said valves respectively to the upper portions of the Wheels 15, 16. Stops 27, 28 are formed on the inner end portions of the valves 23, 24 and are adapted to engage the inner surfaces of side walls of the chute and prevent accidental removal of the valves therefrom, the construction being such that the valves may be inserted or removed by hand as desired by tilting the valves. Stops 29, 30 are fixed to the valves 23, 24 and spaced so as to engage, at times, the outer surfaces of the side walls of the chute 10 and determine inward movement of the valves. It is designed that the inner ends of the valves will abut each other coincident with the engagement of the stops 29, 30 with the chute, and at such time the valves cut off the flow of substance from the hopper through the chute. A notch 31 is formed in the upper outer portion of each wheel 15, 16 and a bar 32 is mounted in each wheel, removably and replaceably, and extends across said notch. Veight 33 are mounted. in selected numbers on the bars 32, the number thereof being varied relative to the weight of the container 22 and its contents and connected parts. Flap valves 34;, 35 are mounted in the lower end of and form a bottom for the container 22 and are carried on rods 36, 37 parallel with each other and pivoted to the container. The rods 36, 37 are formed with downturned end portions connected by a retractile coil spring 38 at the rear side of the container and said rods also are formed with upturned ends at the front side of the container. A stub shaft 39 is pivoted in and extends forwardly from the front side of the container 22 and a cross-head 10 is fixed thereto. Rods A1, 42 pivotally connect the upturned ends of the rods 36, 37 to the ends of the cross-head 10. A hand wheel 13 is fixed to the outer end of the stub shaft 39.

In practical use, the weights 33 are ad- .closes the valves 28,

justed to give the desired counterbalance, a bag or carton 44 is placed beneath the container 22 and the parts are permitted to assume the relative positions shown in Figure 1. The valves 23, 24 being in open positions, substance flows through the chute 1.0 into the container and fills the same to the degree permitted by the weights and moves the container downwardly, which movement of the container is communicated through the hanger bars 20, 21 and rotatesthe wheels 15, 16. The movement of the wheels 15, 16 2% and cuts off flow through the chute. Then the bottom flapvalves 3- 35 are opened by manual operation of the wheel 43 and the contents of the container are dumped into the bag or carton 44, the container being held down manually during, the latter dumping. The wheel l3 is released, the flap-valves return to closing position under the pull of the spring 38 and the container 22 and connected parts assume struction shown as the same may be modified within the scope of the appended claims.

I claim as my invention 1. A measuring device, comprising a chute, valves slidingly mounted in said chute, counterbalancing wheels, connections between said wheels and valves, hangers on said wheels, a container carried by said hangers beneath said chute, and means for dumping the contents of said container.

2. Counter-balancing wheels, each formed with a notch, a bar in said wheel extending across said notch and weights on said bar, said weights being removable and replaceable.

3. Counterbalancing wheels, a lever, rods connecting said wheels and lever, a container, and hangers for suspending said container from both of said wheels.

4. A container, flap-valves mounted therein, rods carrying" said valves, a spring connecting said rods and manually-operated de vices connecting said rods and adapted for operation independent of and by said spring.

Signed at Turner, in the county of Jasper and State of Iowa, this 21 day of: February, 1922.
